A. B. C. D.Answer - B and C.
The specifics for high performance computing are given in the AWS Documentation.
Option A is invalid because this will not give you the desired high performance capabilities.
Option D is invalid because this is not a core design requirement.

The two options to consider during the implementation process for hosting a set of high-performance computing nodes that will process images and videos are:
B. Consider using C5 instances: Amazon EC2 C5 instances are designed for compute-intensive workloads and offer excellent performance for compute-optimized workloads like image and video processing. They come with custom 2nd Generation Intel Xeon Scalable Processors (Cascade Lake) with a sustained all-core turbo frequency of up to 3.6 GHz, and can deliver up to 25 Gbps of network bandwidth.
A. Consider placing the instances in a placement group: An Amazon EC2 placement group is a logical grouping of instances within a single Availability Zone. Placement groups are recommended for applications that need low-latency network performance, or for applications that benefit from having the instances located physically close to each other. By launching instances in a placement group, the instances can communicate with each other using full bisection bandwidth and low latency. This can be beneficial for applications like image and video processing, which require high network performance and low latency.
Options A and D can be ruled out: A. Consider using t2.large instances: T2 instances are burstable instances that are designed for general-purpose workloads that do not require sustained high CPU performance. However, image and video processing are compute-intensive workloads and require sustained high CPU performance, so t2.large instances are not the best fit for this use case.
D. Consider using Linux-based AMIs: The choice of the operating system does not directly impact the performance of the instance. Both Windows and Linux-based AMIs can be used for image and video processing. However, Linux-based AMIs may offer some advantages like better performance and flexibility, as well as the ability to customize the operating system to better meet the needs of the application. However, this is not a major consideration when choosing instance types for high-performance computing.
Therefore, the two options to consider during the implementation process for hosting a set of high-performance computing nodes that will process images and videos are using C5 instances and placing the instances in a placement group.
